Regarding older text games:
They would not however be computer games as there isn't generally an AI involved. I'm not sure if there are any, at least of the older generation, that do include a computer player.
Huh? Will Crowther's original Adventure (c. 1975) included dwarves that wandered through the maze and initiated combat. Don Woods expanded Adventure and released it (1977) in a form that included a pirate whose behavior was a little more complex. The thief of Dungeon/Zork (1977) is more complex still. They most definitely interacted with the player and moved through the shared environment, using instructions in the form of code executed by a computer. The command line parser definitely required a computer to work.
You can see the source code for Crowther's original Adventure discussed here:

Early text games were often played on printer terminals, so the "glass teletype" is not really the defining factor here. I remember going through reams and reams of paper in the computer room in the early/mid 80s.
